Secure with Adhesive

- This step is especially important if you plan to transport your reef.
Optional Glitter
- For a magical touch, sprinkle some non-toxic glitter to represent sunlight dancing on the water’s surface.
Final Touches
- If using a wet version, slowly add water while ensuring not to disturb your decorations.
- Seal the jar with the lid, and your Reef in a Jar is complete!
Tips & Variations
- Color Scheme: Instead of traditional ocean colors, consider a fantasy theme with purples and pinks.
